Abstract

Process for obtaining a colloidal dispersion of a rare-earth compound in aqueous medium. The process is characterised in that it consists in reacting a rare-earth oxide with a controlled quantity of a water-soluble monovalent acid which has a pka of between 2.5 and 5.0 and then heating the reaction mixture obtained. The invention is particularly well suited to the preparation of a colloidal dispersion of an yttric rare-earth compound.
